Abstract

The invention relates to an absorption agent for selectively removing hydrogen sulphide from a fluid flow containing carbon dioxide and hydrogen sulphide, containing a) 10 to 70 wt.% of at least one sterically-hindered secondary amine that has at least one ether group and/or at least one hydroxyl group in the molecule; b) at least one non-aqueous solvent that has at least two functional groups, selected from ether groups and hydroxyl groups, in the molecule, and c) a cosolvent where appropriate; wherein the hydroxyl group density of the absorption agent ρAbs lies in the range of 8.5 to 35 mol(OH)/kg. Moreover, a method is described for selectively removing hydrogen sulphide from a fluid flow containing carbon dioxide and hydrogen sulphide, said fluid flow being brought into contact with the absorption agent. The absorption agent is characterised by a good regeneration capacity and high cyclic acid gas capacity.
